Joachim Protze 48b8a4b519 [OMPT] Handling of the events of initial-task-begin and initial-task-end
OpenMP 5.0 says that the callback for the events initial-task-begin and
initial-task-end has to be ompt_callback_implicit_task.

Joachim Protze 2b46d30fc7 [OMPT] Second chunk of final OMPT 5.0 interface updates
The omp-tools.h file is generated from the OpenMP spec to ensure that the interface
is implemented as specified.
The other changes are necessary to update the interface implementation to the
final version as published in 5.0.
The omp-tools.h header was previously called ompt.h, currently a copy under this name
is installed for legacy tools.

Joachim Protze 0e0d6cdd58 [OMPT] First chunk of final OMPT 5.0 interface updates
This patch updates the implementation of the ompt_frame_t, ompt_wait_id_t
and ompt_state_t. The final version of the OpenMP 5.0 spec added the "t"
for these types.
Furthermore the structure for ompt_frame_t changed and allows to specify
that the reenter frame belongs to the runtime.

Jonas Hahnfeld 3c6595d65d [OMPT] Fix test parallel/not_enough_threads.c
Upcoming changes to FileCheck will modify CHECK-DAG to not match
overlapping regions of the input. This test was found to be affected
because it expects to find four threads to invoke events of type
ompt_event_implicit_task_begin. It turns out this is wrong because
OMP_THREAD_LIMIT is set to 2, so there are only two threads. The
rest of the test got it right so it went unnoticed until now.

(Rewrite test and apply clang-format to it as discussed in the past.)

Joachim Protze 633bc4ca99 [OMPT] Add annotations to testcases that are expected to fail when using certain compilers
Reasons for expected failures are mainly bugs when using lables in OpenMP regions
or missing support of some OpenMP features.
For some worksharing clauses, support to distinguish the kind of workshare was
added just recently.

If an issue was fixed in a minor release version of a compiler, we flag the
test as unsupported for this compiler version to avoid false positives.
Same for fixes that where backported to older compiler versions.

The code is tested to work with latest clang, GNU and Intel compiler. The implementation
is optimized for low overhead when no tool is attached shifting the cost to execution with
tool attached.

This patch does not implement OMPT for libomptarget.

Jonas Hahnfeld dd9a05d5d8 [OMPT] save exit address to lwt if available
In case, the current team is a serialized team (lwt), the frame information should be written to this data structure.

Jonas Hahnfeld 28ea24bba7 [OMPT] fix __ompt_get_teaminfo to consult lwt entries of parent teams
The comment already states, that this function should work similarly as __ompt_get_taskinfo.

The function only looked for lwt entries of the current team, but not when unrolling the parents. This fix aligns the implementation to __ompt_get_taskinfo.

The new test case creates a single theaded team (->lwt) and then a nested active team.
Before the innermost print_id(1) would deliver a different team then the outer print_id(0).

Jonas Hahnfeld 8a27064e05 [OMPT] Reset task exit frame when execution is finished
The exit address is set when execution of a task is started and should be reset as soon as the execution is finished.
Especially for the asm implementation of __kmp_invoke_microtask, resetting in this call would be painfull, so reset just after the invokation.

The testcase shows the effect of this patch:
Before, the implicit barriers at the end of an implicit task would see an exit address for the implicit task.

This barrier is a task scheduling point. Thus, any explicit task scheduled there would see an exit, but no reenter address for the implicit task.

Jonas Hahnfeld fd0614d830 [OMPT] Align implementation of reenter frame address to latest (frozen) version of OMPT spec
The latest OMPT spec changed the semantic of a tasks reenter frame to be the application frame, that will be entered, when the runtime frame drops.
Before it was the last frame in the runtime. This doesn't work for some gcc execution pathes or even clang generated code for :
Since there is no runtime frame between the executed task and the encountering task.

The test case compares exit and reenter addresses against addresses captured in application code

OMPT tests can check for right frame information of tasks:
 * parent_task_frame was directly printed as a pointer, but actually points to a struct ompt_frame {void*, void*}
 * NULL is printed in the beginning of execution and loaded to FileChecker variable [[NULL]]
 * implicit tasks now also print their frame information
 * macro to print frame address from application
 * print task info for barrier begin

Jonas Hahnfeld c804301113 [OMPT] Create infrastructure and add first tests for OMPT
Some basic checks next to the implementation should futher lower the
possibility to introduce regressions. (Note that this would have catched
the ordering issue fixed in rL258866 and pointed to rL263940.)

The tests are implementation dependent in one point because they assume that
thread ids are assigned in ascending order. This is not defined by the standard
but currently ensured in libomp. We have to think about another way of ordering
the threads should this ever be subject to change...

Note that this isn't aiming at replacing the implementation independent
